get_financial_statements

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description does not disclose behavioral traits like read-only nature, required permissions, rate limits, or response structure. It only conveys parameter mappings, not tool behavior.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is compact and front-loaded, using bullet-like format for parameters. The bilingual content adds minimal redundancy but overall efficient. Could be shortened slightly by removing duplicate Chinese labels.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given 5 parameters and no output schema, the description fails to explain the return format, period count (num default), or code format. Essential context for a data-retrieval tool is missing, leaving the agent underinformed about output structure.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Despite 0% schema coverage, the description adds meaning for statement_type (enum mapping), financial_type (period mappings), and currency_code (ISO 4217 with native currency hint). It does not explain num or code, but code is standard and num is inferrable.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool retrieves financial statements (income, balance sheet, cash flow, key indicators) with bilingual labels, making the verb+resource explicit and distinct from sibling tools like get_analyst_consensus or get_company_profile.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus siblings. It lacks explicit context for when to choose this over alternatives such as get_kline or get_earnings_calendar.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
